new fav after school snack: baked (portable) bean and cheese tostadas

We have a new favorite snack around here.  It's quick, protein-packed and portable. 

My kids now get home at 2 different times, both famished. 

I want to come up with a stash of snack ideas that I can make once (in a minimal amount of time... like 10 minutes max) and serve twice.

And feel good about serving. 

 That's a biggie. I'm not going to give them crappy snacks.

And if it's something I might like to munch on too? Even better. 

Baked Portable Tostadas

(makes 4 tostadas / 2 after school snacks)

4 small organic corn tortillas
about 1/2 cup shredded cheese
about 1/2 cup black beans
optional: 1/2 cup sliced veggies, pickled jalapenos and/or salsa

Preheat oven to 375. Place tortillas on a rimmed baking sheet. Sprinkle with cheese, then black beans. Bake on lowest rack for about 10 minutes, or until cheese is melted and tortilla is crisp (so you can easily pick it up). Serve warm or room temp.
